TY - GEN TI - Vitamin B2 supplementation for laying and parent hens in organic poultry systems (RELACS Practice abstract) ID - orgprints39804 A1 - Leiber, Florian A1 - Quander-Stoll, Nele A1 - Ayrle, Hannah N2 - This practice abstract provides recommendations for organic poultry systems to meet the Vitamin B2 needs of the animals. Data from project experiments indicate that hens in or- ganic systems can be supplemented with a maximum level of 4.0 mg/kg feed without impacting the performance and animal health of the hens and their offspring. This level of supplementation is lower than the 5-7mg/kg feed recom- mended by Blum et al. (2015). This tool is recommended for organic poultry farmers across Europe.
